摘要
ANSYS作为一个大型通用有限元分析软件，在分析土壤、堆石体等散粒状材料模式上仅提供了Drucker-Prager材料，本文通过ANSYS参数化设计语言(APDL)在ANSYS中加入目前广泛应用与土体、堆石体的邓肯—张本构模型，并实现采用中点增量法的三维非线性有限元分析计算。最后通过一个工程实例的计算验证了算法的实用性和可靠性。
As a common software based on FEA in CAE field, ANSYS provided only Drucker Prager material in dealing with loose or piecemeal material such as soil and rockfill. The second development was made by adding Duncan Chang stress strain relationships to the ANSYS with the APDL, moreover 3D nonlinear analysis was conducted which indicated the practicality and reliability of the analysis.
